Hello everybody,
On my system, the gcc toolchain does not support the
-fzero-call-used-regs option.
With PTXDIST 2025.09.0 this causes the build of OpenSSL 3.5.2 to fail.
An ad-hoc patch is trivial:
I removed the -fzero-call-used-regs=used-gpr flag from
openssl-3.5.2/Configurations/20-debian.conf (see attached patch).
My question is: would it be possible to integrate a more general solution
into PTXDIST, so that the build works regardless of whether the toolchain
supports this GCC option?
Best regards,
Ruggero Rossi
